FORSTNER PATTERN BIT - FO-350
35mm Dia x 3/8 Shankk
High Speed Steel Forstner Bits
Unlike the standard twist bit, Forstner bits are optimized for woodworking applications and cut exceptionally precise, clean-edged holes in wood. Because they're designed to produce a minimum amount of tear-out when exiting the material, Forstner bits are the best bit for drilling through holes. Forstner bits drill a flat-bottomed hole, making them a necessary tool for many hardware installations where a precise depth of mortise is required.
Forstner bits are guided by the wide outside rim of the bit, unlike most drill bits, which are guided by the tip. Because of that, they can be used along with a drill press to drill angled holes, holes that partially overlap, and holes on the edge of the material. They are really the only bit that's entirely suitable for drilling overlapping guide holes for a rectangular mortise, or for other precision boring operations where the hole needs to be at an angle to the surface of the material.
Drill pocket-holes, flat-bottom holes*, etc., using any 3/8" or larger portable drill or stationary drill press. Forstner pattern bits are well known for their ability to drill clean and chip-free holes in wood. Amana Tool® uses only the finest quality tool steel, precision machined and ground on state-of-the-art equipment. Large gullets milled in the tool body provide exceptional chip clearance.
Note: A small pilot hole used for centering will be present on flat bottom holes.
